Curtain wall buildings, such as skyscrapers, with their large window-to-wall ratio, are often not energy efficient because of poor insulation. RetroWAL™ is an interior curtain wall retrofit system by Thermolite Windows that has been found to improve energy performance in buildings by over 20%.
RetroWAL™ has also been found to increase the existing glass R value by 3, 5 and 10 times depending on the selected system.
